Q: How to benchmark a Linux VPS with VH Benchmark Script?

Benchmarking a Linux VPS refers to measuring CPU performance, disk I/O speed, and network bandwidth to evaluate the real performance of a virtual server (VPS). You can perform this benchmark quickly using the VH Benchmark Script by executing a single Bash command: curl -Lso- https://mirrors.viethosting.com/scripts/vh-benchmark.sh | bash Expert Insight: VH Benchmark Script includes dedicated test nodes for major Vietnamese ISPs such as VNPT, Viettel, and FPT, providing realistic network speed results for users located in Vietnam.

Q: What is a self-hosted OpenVPN server?

A self-hosted OpenVPN server is a private virtual private network system installed directly on a VPS or dedicated server that you control. Instead of sharing infrastructure with thousands of users on commercial VPN platforms, you maintain absolute control over the server environment, encryption protocols, and network traffic. Expert Insight: Routing all your internet traffic through a dedicated static IPv4 address eliminates the risk of shared IP blacklisting, making this setup ideal for remote workers and securing business accounts.

Q: What operating systems support OpenVPN servers?

OpenVPN servers are natively supported by most modern Linux distributions. Linux is the preferred environment because it provides robust network routing capabilities and efficient firewall management. Supported systems typically include: Ubuntu 22.04 / 24.04 LTS AlmaLinux 8 / 9 / 10 Rocky Linux 8 / 9 / 10 Other RHEL-based distributions

Q: How to automatically install an OpenVPN server on Linux?

You can automatically install a secure OpenVPN server on your Linux VPS by running the following command via SSH with root privileges: curl -O https://mirrors.viethosting.com/scripts/openvpn-installer.sh && bash openvpn-installer.sh The script instantly handles CA generation, configures the firewall and applies NAT masquerade rules for outbound traffic. Security Note: This installer is hosted on VietHosting's internal mirrors for safety, pre-hardened to enforce TLS 1.2+, and automatically configures Logrotate to manage server storage efficiently.

2.4. Traceroute / tcptraceroute

Traceroute is a classic diagnostic tool used to track the route packets take from your server to a destination host and identify exactly where network latency or routing issues occur. Unlike standard ping, tcptraceroute uses TCP packets to bypass firewalls that block ICMP traffic.

Usage & Installation:

On Windows (Built-in): Open CMD and use the command tracert [IP/Domain].
On Linux (AlmaLinux / Rocky Linux / RHEL 8+):
dnf install traceroute tcptraceroute -y
On Linux (Ubuntu / Debian):
apt install traceroute tcptraceroute -y
